What type of intrusive features form when magma is injected into fractures cutting across preexisting rock layers?
A fault
What else can I help you with?
Are sills and dikes an example of intrusive igneous activity?
Yes they are. Dikes are tabular discordant bodies that are produced when magma is injected into fractures and Sills are tabular plutons formed when magma is injected along sedimentary bedding surfaces.
Are sills tabular discordant bodies that are produced when magma is injected into fractures?
Yes, sills are tabular discordant bodies formed when magma intrudes into pre-existing fractures and solidifies between layers of existing rock. They are characterized by their flat, parallel orientation with the surrounding rock layers.
What kind of rock is dike in geology?
A dike is a type of rock that cuts across the layers of its surroundings. They're often made of magma, but sediments can also form dikes. If a rock cuts along the layers of its surroundings, it's a sill.
Which is older the sill or the rock surrounding it?
The rock surrounding the sill is typically older because the sill is an intrusive igneous rock body that forms when magma is injected into existing rock and solidified.
What type of plutonic body is Mount Cristo Rey?
Mount Cristo Rey is a laccolith, which is a type of intrusive igneous rock formation that occurs when magma is injected between layers of sedimentary rock and causes the overlying rock layers to arch upward.
Which type of intrusive feature forms when magma is injected into fractures cutting across preexisting rock layers?
Dikes are intrusive features that form when magma is injected into fractures that cut across preexisting rock layers. Dikes are tabular structures that can range in width from a few centimeters to tens of meters and can extend for kilometers.
Which type of intrusive feature when magma is injected into fractures cutting across preexisting rock layers?
sill

What is the narrow tube-like body of intrusive igneous rock that cuts across existing rock called?
What is the narrow tube-like body of intrusive igneous rock that cuts across existing rock calle
Small intrusions parallel to existing rock?
These small intrusions are likely dikes, which are vertical or near-vertical sheet-like bodies of intrusive igneous rock that cut across the existing rock layers. They are formed when magma is injected into existing fractures and solidifies underground. Dikes can provide insight into the geological history of an area and the direction of magma flow.
A laccolith is an example of?
A laccolith is an igneous intrusion that occurs when magma is injected between layers of sedimentary rock, causing the overlying rocks to be domed upwards. They are characterized by their mushroom-like shape and are found in geologically young mountain ranges.
What is an intrusive igneous rock body that is tabular and concordant?
A sill is an intrusive igneous rock body that is tabular and concordant, meaning it is parallel to the layering of the surrounding rock. Sills form when magma is injected between existing rock layers and solidifies underground.
Are laccoliths an example of intrusive igneous activity?
Yes they are. Laccoliths can lift the sedementary strata they penetrate. Laccoliths are igneous rock forcibly injected between sedimentary strata.
A thin sheet of magma can harden underground to form a dike?
Yes, when magma is injected into fractures in the Earth's crust and cools and solidifies underground, it forms a sheet-like geologic feature called a dike. Dikes are made of intrusive igneous rock and can be composed of materials such as basalt, granite, or diorite. They are typically vertical or near-vertical in orientation and can range in thickness from a few centimeters to several meters.
Intrusive igneous rock body that is tabular and concordant?
A sill is a type of intrusive igneous rock body that is tabular and concordant, meaning it is parallel to the layering of the surrounding rock. Sills are formed when magma is injected into existing rock layers and solidifies underground. They are often found in sedimentary rock formations.
